Mahendra Suri was a Jain. Jainism began around the sixth century BC and the religion had a strong influence on mathematics particularly in the last couple of centuries BC. By the time of Mahendra Suri, however, Jainism had lost support as a national religion and was much less vigorous. It had been influenced by Islam and in particular Islamic astronomy came to form a part of the background. However, Pingree in [4] writes that this filtering of Islamic astronomy into Indian culture was:-

... not allowed to affect in any way the structure of the traditional science.

Mahendra Suri was a pupil of Madana Suri. He is famed as the first person to write a Sanskrit treatise on the astrolabe. Ohashi writes in [3] of the early history of the astrolabe in the Delhi Sultanate in India:-

The astrolabe was introduced into India at the time of Firuz Shah Tughluq (reign AD 1351 - 88), and Mahendra Suri wrote the first Sanskrit treatise on the astrolabe entitled Yantraraja (AD 1370).
